Although it receives less attention, (Lewis in Noûs 13:455–476, 1979. https://doi.org/10.2307/2215339) admitted that the branching-time(-like) model fits a wide range of counterfactuals, including (Nix) ‘If Nixon had pressed the button, there would have been a nuclear war’, which was raised by (Fine in Mind 84:451–458, 1975). However, Lewis then claimed that similarity analysis is more general than temporality analysis. In this paper, we do not scrutinise his claim. Instead, we re-analyse (Nix) not only model-theoretically but also proof-theoretically from the ‘meaning-as-use’ (...) and ‘inferentialist’ points of view. Then, we re-formalise (Nix) in a natural extension of hybrid tense logic, which we refer to as hybrid tense logic for temporal conditionals (HTL$$_{TC}$$ TC ). Consequently, we find that not only among counterfactuals, but also among indicatives, there is a wide range of conditionals whose formalisation in HTL$$_{TC}$$ TC is appropriate. We refer to these conditionals as temporal conditionals. This suggests a new logical generality that temporality analysis has but similarity analysis does not, from which emerges a new logical perspective on conditionals in general: temporal ones and others.

Lewis (Noûs 13:455–476, 1979) claimed that branching-time(-like) models can be derived from his sphere models. However, he did not present any specific construction of branching-time(-like) models from his sphere models formally. Meanwhile, Hosokawa (in: Modern logic of modality and its philosophical range: counterfactuals, Gettier problem, and information flow, Tokyo Metropolitan University, 2018) presented a logico-mathematically strict manner in which sphere models can be reconstructed from branching-time models. Subsequently, Hosokawa (J Logic Lang Inf 32:677–706, 2023) presented a proof-theoretically refined (...) version of hybrid tense logic for a certain type of conditionals, which is referred to as hybrid tense logic for temporal conditionals ( $$\textbf{HTL}_{TC}$$ ). In this paper, we interpret a hybrid version $${\textbf{V}}_{\mathcal {HC(@, \downarrow )}}$$ of Lewis’s counterfactual logic $${\textbf{V}}$$ into $$\textbf{HTL}_{TC}$$, and then prove that $$\textbf{HTL}_{TC}$$ is more expressive than $${\textbf{V}}_{\mathcal {HC(@, \downarrow )}}$$ on the class of temporal sphere models, i.e., sphere models derived from a type of branching-time models.

Establishment of cell lineage identity from multipotent progenitors is controlled by cooperative actions of lineage‐specific and stably expressed transcription factors, combined with input from environmental signals. Lineage‐specific master transcription factors activate and repress gene expression by recruiting consistently expressed transcription factors and chromatin modifiers to their target loci. Recent technical advances in genome‐wide and multi‐omics analysis have shed light on unexpected mechanisms that underlie more complicated actions of transcription factors in cell fate decisions. In this review, we discuss functional dynamics (...) of stably expressed and continuously required factors, Notch and Runx family members, throughout developmental stages of early T cell development in the thymus. Pre‐ and post‐commitment stage‐specific transcription factors induce dynamic redeployment of Notch and Runx binding genomic regions. Thus, together with stage‐specific transcription factors, shared transcription factors across distinct developmental stages regulate acquisition of T lineage identity. (shrink)

Web-based learning resources provide learners with hyperspace where they can navigate in a self-directed way to learn the contents included in the Web pages. The navigation involves making a sequence of the pages visited, which is called navigation path. However, learners often fail in making the navigation path due to a cognitive overload, which is caused by diverse cognitive efforts at comprehending the contents in Web pages, and monitoring the navigation process such as planning and reflection of navigation path. In (...) the self-directed learning, in particular, it is difficult for learners to maintain the navigation monitoring. Focusing on navigation planning, this paper addresses the issue of how to facilitate learners' navigation monitoring to promote their learning in hyperspace provided by Web-based learning resources. Our approach to this issue is to provide learners with a space, in which they can see through the learning resources to plan a navigation path, apart from hyperspace. In this paper, we also demonstrate an assistant system for the navigation planning, which is composed of hyperspace map, page previewer, and path previewer. These facilities give learners an overview of Web pages and navigation path to help them make a navigation path plan without visiting Web pages in hyperspace. This paper also describes a case study with the assistant system. The results indicate that the system facilitates navigation particularly in a more complicated hyperspace. (shrink)

Quantum walks exhibit different properties compared with classical random walks, most notably by linear spreading and localization. In the meantime, random walks that replicate quantum walks, which we refer to as quantum-walk-replicating random walks, have been studied in the literature where the eventual properties of QWRW coincide with those of QWs. However, we consider that the unique attributes of QWRWs have not been fully utilized in the former studies to obtain deeper or new insights into QWs. In this paper, we (...) highlight the directivity of one-dimensional discrete quantum walks via QWRWs. By exploiting the fact that QWRW allows trajectories of individual walkers to be considered, we first discuss the determination of future directions of QWRWs, through which the effect of linear spreading and localization is manifested in another way. Furthermore, the transition probabilities of QWRWs can also be visualized and show a highly complex shape, representing QWs in a novel way. Moreover, we discuss the first return time to the origin between RWs and QWs, which is made possible via the notion of QWRWs. We observe that the first return time statistics of QWs are quite different from RWs, caused by both the linear spreading and localization properties of QWs. (shrink)

Poor sleep quality negatively affects memory performance, and working memory in particular. We investigated sleep habits related to sleep quality including sleep duration, daytime nap duration, nap frequency, and dream content recall frequency (DCRF). Declarative working memory can be subdivided into verbal working memory (VWM) and visuospatial working memory (VSWM). We hypothesized that sleep habits would have different effects on VWM and VSWM. To our knowledge, our study is the first to investigate differences between VWM and VSWM related to daytime (...) nap duration, nap frequency, and DCRF. Furthermore, we tested the hypothesis that the effects of duration and frequency of daytime naps and DCRF on VWM and VSWM differed according to sex. We assessed 779 healthy right-handed individuals (434 males and 345 females; mean age: 20.7 ± 1.8 years) using a digit span forward and backward VWM task, a forward and backward VSWM task, and sleep habits scales. A correlation analysis was used to test the relationships between VWM capacity (VWMC) and VSWM capacity (VSWMC) scores and sleep duration, nap duration, nap frequency, and DCRF. Furthermore, multiple regression analyses were conducted to identify factors associated with VWMC and VSWMC scores and to identify sex-related differences. We found significant positive correlations between VSWMC and nap duration and DCRF, and between VWMC and sleep duration in all subjects. Furthermore, we found that working memory capacity (WMC) was positively correlated with nap duration in males and with sleep duration in females, and DCRF was positively correlated with VSWMC in females. Our finding of sex-related differences in the effects of sleep habits on WMC has not been reported previously. The associations between WMC and sleep habits differed according to sex because of differences in the underlying neural correlates of VWM and VSWM, and effectiveness of the sleep habits in males and females.

A 2012 review article for Metascience which explains Mach's realistic brand of empiricism, contrasting it with the common phenomenalist reading of Mach by John Blackmore in two recent books.

In his project of going beyond the “modern worldview,” Hiromatsu Wataru attached great importance to Ernst Mach’s philosophical thought and Einstein’s theory of relativity as challenging the premises of modern philosophy, which he characterized as substantialist and bound by the subject / object schema. This paper surveys Hiromatsu’s analysis of Mach’s phenomenalist element-monism, specifically his critique of Mach’s insufficient break with modern philosophy; his inquiry into Einstein’s relativity theory with a focus on its intersubjective cognitive structure; and the way he (...) extends his views on these themes to a general ontological-epistemological theory of the “fourfold structure.” Finally, it examines questions about Hiromatsu’s arguments regarding the tension between the dimensions of synchronic structure and structuring movement. An earlier version of this paper can be found as “Philosophers” in John T. Blackmore, Itagaki Ryōichi, and Tanaka Setsuko, eds., Ernst Mach’s Influence Spreads, 425–76. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:The Japan Society for Buddhist-Christian Studies:Report on the 39th Annual Meeting August 18–19, 2021Kunihiko TerasawaThe 2021 annual conference of the Japan Society for Buddhist-Christian Studies was held online by Zoom. Five presentations were given on the theme of "Religion and Literature."August 18 (Three Presentations)First, President of the Japan-SBCS and professor emeritus at Sophia University, Yutaka Tanaka, presented "Hosokawa Garasha (Gracia)," which was about a Kirishitan (Christian) woman martyr (...) in the sixteenth century (1563–1600 ce) in Japan. Garasha was a wife of the feudal lord Hosokawa in Kyushu. The enemy attacked Garasha's castle. Instead of being killed by enemies, for the sake of honor, she chose to be killed by ritual suicide by her own vassals. Garasha's servants wanted to die with her according to tradition, but she let them run away. The servants testified about her death to Jesuit missionaries. According to the missionaries, Garasha chose to be killed by her vassals because it was honorable as the wife of Lord Hosokawa. If she would have chosen to run away, her husband would have become anti-Christian, persecuting missionaries, and believers. In this way, she became a martyr. According to missionaries, Garasha always loved reading the Imitatio Christi longing for the experience of Christ's cross.Tanaka explained the story of Garasha was spread in the sixteenth–seventeenth-century Europe through Jesuit missionaries. This story was composed to become an opera of Mulier Fortis (a brave lady) and played at the palace of Vienna in 1698.Second, Kunihiko Terasawa, an associate professor at Wartburg College, presented about his research in South Korea and Hong Kong during his sabbatical in 2019–2020. Terasawa's research project was titled "Interreligious/Transnational Solidarity of Religion as Resistance to Ultranationalist Populism in East Asia and Pacific Rim." In South Korea, he was a visiting professor at Sogang University, a Jesuit college, focused on how reconciliation could be possible between Korea and Japan through Buddhist-Christian dialogue. Terasawa visited churches, temples, Christian/Buddhist universities, and Seoul National University for discussions with youth and scholars, and presented four times during his time. He also interviewed comfort women and visited the Sodemon prison that the Japanese' occupation government built. Terasawa was [End Page 389] eventually interviewed by a national daily newspaper for their piece, titled, "The Improvement of Korea-Japan Relationship through Repentance and Forgiveness."Terasawa was also a visiting professor at Hang Seng University of Hong Kong and taught a course on "Asian Religions and Society." Terasawa interviewed students, scholars, and religious leaders, and found that many Christians students are involved in democratic movements. However, it has not been easy to create solidarity between Christianity and Buddhism for democratic movements. Hong Kong Buddhists have had resentment toward Christianity due to the British Hong Kong government's leniency toward Christianity. The Buddhists, therefore, are more inclined to support the current Hong Kong government backed by the Chinese Communist government. The Buddhists appear to be politically indifferent, focusing on inner mindfulness or meditations. Thus, Hong Kong students and professors are focused less on past resentments and more on the future, and thus are vital in creating solidarity among Christians, Buddhists, and Muslims for democracy and human rights.Third, Yoshio Tsuruoka, a professor emeritus at Tokyo University, presented "How to read the poems of St. John the Cross with reference to the 'language' philosophy of Shizuteru Ueda." Ueda was a professor at Kyo to University, specializing in the philosophies of Nishida Kitaro and Meister Eckhart. Tsuruoka explained St. John the Cross'sjourney, most notably, how he became a mystic in his relation to Teresa de Ávila and ended up writing poems during his confinement time. His poems are "songs of love,""dark night," and "fire of love," and symbolize the romantic relationship between lover and loved without particular nouns. This love relationship of "I"–"Thou" implies his love relationship with God. Tsuruoka explored the love language of "I"–"Thou" of John the Cross which indicates the essence of language. Language is not just a written word or descriptive one, but an utterance from a human subject of person to the "other" person in relationship. That is why... (shrink)
